Description

Verfahren zur Herstellung einer Einschleifpaste Als Träger der wirkenden Mittel, Schmirgel, Bimsstein usw., werden für Einschleifpasten vornehmlich Öle, Fette, Glycerin oder Seifenlösungen verwendet. Es hat sich in der Praxis gezeigt, daß diese Träger ein allmähliches Absetzen der festen Bestandteile bei längerer Aufbewahrung der Pasten nicht zu verhindern vermögen:--Man hat bereits versucht, diesen Übelstand dadurch zu beseitigen, daß man der Masse voluminöse Füllköper zufügte. Diese Stoffe setzen jedoch mehr oderweniger die Schleifkraft der ganzen Masse herab.Process for the production of a grinding paste as a carrier of the acting Medium, emery, pumice stone, etc., are mainly oils, Fats, glycerine or soap solutions are used. It has been shown in practice that these carriers have a gradual settling of the solid constituents over time Are unable to prevent the pastes from being stored: - An attempt has already been made to to eliminate this drawback by adding voluminous fillers to the mass. However, these substances reduce the grinding force of the whole mass to a greater or lesser extent.

Nach der Erfindung wird der angegebene Nachteil dadurch beseitigt, daß man als Träger der schleifenden Mittel konzentrierte Lösungen hygroskopischer Salze benutzt. Diese Lösungen besitzen eine größere Viskosität als die oben angegebenen Stoffe und ihr spezifisches Gewicht liegt auch über demjenigen derselben.According to the invention, the specified disadvantage is eliminated by that one as a carrier of the abrasive means concentrated solutions of hygroscopic Salts used. These solutions have a higher viscosity than those given above Substances and their specific gravity is also higher than that of the same.

Als besonders geeignet haben sich für den angegebenen Zweck Lösungen von milchsauren Alkalien erwiesen. Diese Körper ergeben mit geringen Mengen Wasser eine sirupöse Lösung von hohem spezifischen Gewicht. Zweckmäßig werden dieser Lösung fein gemahlene Metalloxyde, vornehmlich Zinkoxyde oder zinkoxydhaltige Stoffe, wie Lithopone u. dgl., zugefügt und alsdann die Masse gut durchgerührt, bis ein zäher, teigiger Brei erhalten wird. Dieser Brei zeigt alkalische Reaktion. Mit diesemBrei wird das Schleifmittel auf das innigste verrührt. Die alkalische Reaktion wirkt insofern günstig beim Schleifprozeß, als die meist fettigen und öligen oder verharzten Oberflächen der abzuschleifenden Gegenstände leichter entfernt werden. Ebenso werden die oxydierten Oberflächen der meisten Metalle gleichfalls leicht beseitigt. An Stelle von milchsauren Alkalien können auch konzentrierte Lösungen von Chlorcalcium, Chlormagnesium o. dgl., wenn auch nicht mit ganz so günstiger Wirkung, verwendet werden.Solutions have proven to be particularly suitable for the stated purpose proved by lactic acid alkalis. These bodies yield with small amounts of water a syrupy solution of high specific gravity. This solution will be useful finely ground metal oxides, primarily zinc oxides or substances containing zinc oxide, such as Lithopone and the like, added and then the mixture well stirred until a tough, doughy pulp is obtained. This pulp shows an alkaline reaction. With this pulp the abrasive is thoroughly stirred. The alkaline reaction works insofar as favorable in the grinding process as the mostly greasy and oily or gummed up Surfaces of the objects to be abraded can be removed more easily. Likewise be the oxidized surfaces of most metals are also easily removed. At Instead of lactic alkalis, concentrated solutions of calcium chloride, Magnesium chlorine or the like, although not with quite as beneficial effect, is used will.

Die Masse behält, wie bereits angegeben, ihre große Homogenität lange Zeit bei sich und setzt auch bei sehr langer Aufbewahrung infolge ihres hohen spezifischen Gewichtes und ihrer Viskosität die festen Bestandteile nicht ab. Ein weiterer Vorteil der Masse besteht noch darin, daß sie sich erheblich billiger stellt als Pasten, welche unter Verwendung von Glycerin o. dgl. hergestellt sind.As already stated, the mass retains its great homogeneity for a long time Time with itself and sets even with very long storage due to its high specificity Weight and viscosity does not affect the solid components. Another advantage the mass still consists in the fact that it is considerably cheaper than pastes, which are made using glycerin or the like.
